Specification of Letters Patent.

Patented Aug. 13,1991.

Application filed October 31, 1904. Serial No. 230,863;

To all whom it may'eoncern:

. to it known that I, lions -ROYDEN PEIRGE, a citizen of the UnitedStates, residing in the borough of-Man- I especially for coping stone,that is to say, for cutting slabs into sizes for wall facings or thelike. The machine is also adapted to cut st ne in various other ways. I

The machine, though preferably used with a rotating carborund um wheel,is adapted also for use with cutters of various other styles. i

The accompanying drawings illustrate a machine embodying the invention.

Figure 1 is a cross-sectional view showing the cutting headanditssupports in front elevation. Fig. 2 is a side view. Fig. 3 is a planmade in two separate parts.

Figs. 4 and 5 are vertical, transverse sections of the cutter head intwo different positions.

An important feature of the machine, independently of the particularsort of cutter used, is the construction from its holder, lengthwise andtransverse cuts may be made to cut the rough slab into a rectangularcoping. These two movements are preferably obtained by utilizing thelongitudinally-moving bed to secure cuts in a longitudinal direction,and holding said bed stationary while moving the cutter across it to cutin a transverse direction (the cutting edge of the cutter beingpreferably adjustable about a vertical axis).

for the stone is in the form of sin-ordinary planer bed A to which thestone may be clamped, and which receives longitudinal movement by meansof a screw-threaded -shaft B which is connected atone end by means of aworm C with across shaft D. Extending acrossthe 40 bed is afframe whichcarries the cutter and which is composed ofup rightsE and horizontalguides F along which moves thecutter head, which is indicated .as a

whole .by the letter G. The cutter head is carried directly in. acarriage H which slides upon the guides F ofithe cross head and whichreceives its transverse movementfrom a screw-threaded shaft Jpassingthrough a suitably threaded portion of the carriage and fixed atits ends in the uprights E. The head G is ver tically adjustable in-thecarriage H by means of a grooved shaft K working in a spindle worm-wheelL -wl1ich drives a similar worm-wheel .L which is internally threadedand causes an up-and-down' movement of the vertical screw shaft Mfastened in a cross-bar N at the rear of-the head. The guides F are infact the K are provided, for purposes of adjustment, with handwheels Rand S at the front of the machine.

When it is'desired to make a longitudinal cut, the stone is clamped uponthe bed in the usual way, the

--hand-wheel R is, turned to give the desired lateral adjustment to thecutter T, and the hand-wheel S is turned to adjust it vertically. Thecutter is then held with rigidity, which is an important matter, anddnexactly the desired line and level. The cutter is then rotated at a highrate of speed by means of a pulley U on the cutter shaft V, and a belt Wwhich runs to the top of the head G and over a pair of pulleys X and Yto any suitable driving drum pulley Z arranged overhead andat asufficient distance to permit the desired Vertical and lateraladjustments of the cutter. .The usual longitudinal movementof the bed Awill then be effected by pushing the lever a in the direction of thearrow Fig'. 1, which, by means of a link b and lever c,'will throw theclutch block (1 into positidn to engage the shaft D and move the bedaccordingly. The clutch and driving connections may be of any suitablestyle, the clutch block at being splined, for example, upon a powershaft e. For making a transverse cut, means are provided for applyingpower to the shaft J to move the cutter across and through the stone.With a rotating cutter such as .T, it is essential also that the cutterbe adjusted to the direction of the cut. Accordingly the shaft V of theI cutter is mounted in a block f which is held in the lower Referring tothe embodiment illustrated, the holder end of the cutter head G by meansof a circular rib g rotating in a corresponding groove in the lower endof the cutter head. The cutter head is provided with'a movable sectionit for permitting the insertion of the block f. The amount ofangular-movement of the block f is unlimited, and it may be desirable towork it at various angles, but for ordinary purposes the only transversecut desired will be one at i'ight angles to the longitudinal cut. Inorder to determinethe right-angle position the block f is provided witha pin j adapted to fit into either one of two sockets k inllugs katright angles to each other upon the iront oi the cutter head, thelocking pinj being carried by a hand-lever l which is held upward by aspring m.

clutch d have adjacent clutch faces; so that when the As stated above,the details of the clutches are not of importance, but it is preferredto arrange the clutches so as to obtain most easily the operationsdescribed. For example, the power shaft 0 may be driven in one directionby means of a conical pulley p, the shaft being supported in bearings q.The movement in the reverse direction is ohtained irom a pulley 1', bothpulleys r and 7) being loose on the shaft 0. A second clutch block s issplined to the shaft 0 and arranged to engage either the pulley r or thepulley 7) according as it is shifted in 'one direction or the other bymeans of a rod t supported at one end in a bearing (1 and connected atits other end to one arm of a bell-crank-lever u, the other arm of whichis connected by means of a link 1) to a hand lever w at the center andfront of the mach ine.

No claim is made in the present application to the cutting of the stoneby means of a thin wheel of agglomstone adapted to move longitudinally,a common power,

shaft, and a clutch which clutches the cutter or holder alternately tosaid power shatt.

2. A stone cutting apparatus including, in combination, a cutter headG,'a cutter shaft V, a block 1' carrying said cutter shaft andadjustable about a vertical axis in the lower end of said cutter head. ashaft .7 for moving said cutter hezid laterally, and meansloixeluii'hing said shaft J to a power shaft r In witness whereof, -ihave heryunto signed my mime in the presence of two subscribingwitnesses.
